SPECIFICATION forming part of Letters Patent N o. 665,290, dated J anuary 1, 1901.

Application led October 19.00.

To ZZ whom it may concern,.-

Be it known that we, WILLIAM D. WATSON and JOHN A. KNISELY, citizens of 'the United States, residing at Chicago, inthe county of dows, of which the followingis a specification.

Ou r invention relates to improvements in swinging'windows, and more particularly to windows of sheet-metal constructionfsuch,

ent, No. 652,553, granted to William D. Watson June 26,1900. It is well known -to those frames 'and casings of such windows may be constructed and however carefully ttedto each other when rst put in place the 'almost inevitable settling of the building will in many cases cause the windows to bind and stick, so that they canbe operated only with and readj usted at a considerable'ex'pense', and it frequently happens that such overhauling and readjustment are 4repeatedly frequired during the life of the structure.

Avprincipal object of the present invention may bel adjusted within their frames sulficiently to compensate for any ordinary racking or distortion of the casing brought about' by the settling of the building or otherwise;

matters -herein set forth, a'nd particularly fully'understood lfrom the following descriptioh of the construction illustrated lin the ac- Figure 1 is a transverse sectional elevation' of awindow sash and casing made relatively adjustable in accordance with our invention, the section being taken on line l 1 of Fig. 5. Fig. 2 is a transverse sectional elevation taken on line 2 2 of Fig.' l. Fig. 3 is a sectional elevation taken on line 8 3 of Fig. 5. Fig. 4 isan enlarged sectional detail taken on the same plane as Fig. 1. Fig. 5 is a. horizontal sectional detail taken on the plane of line 5 5 of. Fig. l. Fig. 6 is a perspective detail Iof the adjustable pivot with its parts separated.

casing, Which is built into theaperture provided iu the wall ofthe bpilding to receive it. The sash-frame is herein shown as of tubular construction, with an inwardly-'projecting channel 4 extending entirely around' the frame and forming a condensation-gutter, at the bottom of which one or more apertures 5 are desirably provided to permit the escape of any moisture collected therein. The pivot bolts or screws 6, which support the sash, are herein shown as passing through this channel portion 4 and through the adjacent sides of the window-casing and are so located that the weight of the sash always tends to swing it closed. A'suitable chain or othercontrivance (not herein illustrated) may then be provided forV holding the sash open when desired.

'lo permit the sash to be adjusted within the casing, the pivots 6 are adjustably se-Y cured with reference thereto.

ltothe sash by rivets 13. The pivot 6`projects from the plate 9 inwardly through an elongated slot 14, cut through the sash and its reinforcing-plate l2, and enters a threaded aperture 15, which is suitably'located in the .adjacent wall of the window-casing, and

which,'as herein shown, extends also through This is accom i plished in the approved construction shown a reinforcing-plate 16, secured tothe innerV face of said casing by rivets 17. Thev utility of the adjustment thus provided will-b e bett-er understood from a consideration of Fig'. l, in which the casing 2 is assumed to be lracked out of shape by the settling of theV building or otherwise. This tends tocause the sides of the sash to bind on the casing at opposite upper and lower corners, as at 18;

but such tendency may be practically overcome to an extent sufficient vto permit the on its pivotso as to raise it on one side and lower it ou the other, the clamping-screws -being tightened again as soon as the bind is IOO 1 bars project, when the sash is closed, into ver- At the sides of thewindow, however, the

strips or other devices provided for excluding the weather should be of such a nature as to automatically compensate for any angularity resulting between the sides of the sash and casing. To this end the Window is shown as provided, in accordance with the said prior patent, No; 652,553, with spring pressed Weather-bars 21, seated in vertical grooves or recesses 22 inthe sides of the casing 2. These tical grooves 23, formed in the adjacent side` surfaces of the sash, and fit therein so closely as to eiectually keep out both wind and moisture. W'hen the sash is swung on its pivots 6, the weather-bars are'forced back into the recesses 22 by the wedging action of the sash ou the curved surfaces of the bars; but when hesash is returned to its closed position the bars instantly swing forward again into the grooves and seal the openings between the sidesof the sash and casing regardless of the varying width of the 'crack caused by the-irregular 'adjustment between them. (See As herein shown, the weather-bar-sprin'gs 24 are bow-shaped plate-springs that are removably secured to the tubes by screwsv25; butobviously they may be'otherwise formed or provided as desired. It will also be understood that various other changes may be made in the details of the construction de-.
